Spear Spewer

Dissipation Field

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Temur Ascendancy

How it works

1. Cast Spear Spewer by paying .
2. Birgi triggers, adding .
3. Activate Spear Spewer by tapping it, dealing 1 damage to each player.
4. Dissipation Field triggers, returning Spear Spewer from the battlefield to your hand.
5. Repeat.

This loop centers on a clever interaction where casting Spear Spewer for a single red mana triggers Birgi, God of Storytelling to immediately refund that exact cost. Once it resolves, you tap Spear Spewer to ping each player, which cleverly turns Dissipation Field's defensive trigger into a self-bounce engine that returns Spear Spewer right back to your hand. Meanwhile, Temur Ascendancy grants your creatures haste so you are ready to recast them instantly, completing a self-sustaining cycle that endlessly repeats its casting and bouncing.
